Goldman Sachs: AI Spending Accounts for About Half of S&P 500 Earnings Growth — Concentration Brings Risk

Goldman Sachs strategist Ben Snider told CNBC that AI-related capital spending is driving roughly 50% of S&P 500 earnings growth. That lifts the index now, but also concentrates its fate in a handful of hyperscalers and AI suppliers.

Useful takeaways from this story.

Goldman Sachs estimates AI investment is responsible for about half of the S&P 500’s earnings growth, centering gains on a small group of buyers and suppliers.

NVIDIA, Broadcom, and Microsoft sit at the heart of the cycle: massive supplier revenue growth and large hyperscaler capex underpin current index profits.

The setup is earnings-driven with a compressed S&P 500 multiple (roughly 19x), but is vulnerable if hyperscalers cut discretionary AI capex.

The useful part

Oops, something went wrong Skip to navigation Skip to main content Skip to right column Goldman Sachs Says AI Is Driving Half of S&P 500 Earnings Growth. SPY trades near highs with a compressed 19x P/E, but Snider warns half of S&P 500 earnings growth runs through one AI capex cycle. Goldman's positioning indicator is at its lowest since March, offering a selloff cushion, but September seasonality and the upcoming CPI report add near-term risk.

How it works

  • NVIDIA posted Q2 FY27 revenue of $96.22 billion, up 105.8% year over year, with data center at $89.02 billion, per the Q2 FY27 release filed with the SEC.
  • Most S&P 500 companies continue to leave AI-driven earnings accretion out of their reported figures, so the broadening shows up in demand commentary while remaining largely narrative in reported profit.
  • Staging fresh capital over several months, rather than a single lump ahead of the next CPI release and the Fed decision, is worth researching against your own timeline.
  • For anyone researching the index, the reality that half the growth story runs through three names deserves weight in the analysis.
  • It's not 10 ideas, not 10 stocks everyone is talking about, it's what their research points to as the 10 best stocks to buy right now, and it's free.

What to take from it

A falling multiple alongside a rising index is a healthier setup than the reverse, because the gains are backed by realized earnings rather than a re-rating. Concentration Inside the Bull Case If AI capex is funding half of index earnings growth, then a handful of hyperscalers deciding to keep spending is what keeps the average up. Light positioning cushions a selloff because less crowded exposure has less to unwind.

  • Microsoft is on the buyer side, with full-year capex of $115.95 billion and an FY27 capex expectation of roughly $175 billion.
  • Microsoft supports that read: 365 Copilot reached over 30 million paid seats, and commercial remaining performance obligations grew 84% to $678 billion.
